Improvement in paint-brushes



UNITED STATES FRANK H. JORDAN, OF PORTLAND, MAINE.

IMPROVEMENT IN PAINT-BRUSHES.

Specification forming part ofLetters Patent No. 154,397, dated August 25, 1874 application filed May i5, 1874.

To allwhom 'it may concern:

Be it known that I, FRANK H. JORDAN, of Portland, inV the county of Cumberland and State of Maine, have invented certain new and usefullmprovements in Paint-Brushes; and I do hereby declare that the followingis a full, clear, and exact description thereof, which will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

The drawing shows a sectional view of my invention.

The object of my invention is to produce an improved paint-brush. It consists, first, of a movable and detachable plate or diskV having on its lower surface a series of projecting pegs or points, the said plate working within the ferrule of a brush and being held in position by the butt of the` brush-handle, as is hereinafter more fully described; second, in the combination of a handle having a screw upon"`its butt with a ferrule having a female screw to match the screw upon the handle, and a separate removable plate provided with points on its lower surface, the said plate working within the ferrule and operated by the pressure of the handle upon it; third, in the combination of a screw-handle, a ferrule fitted with a screw, a removable plate having points on its lower surface, and a fixed perforated disk.

Having thus given the object of my invention, and in what it consists, I will now proceed to describe in detail its construction and operation.

' c shows the handle ofthe brush, on the lower end of which is the base b, provided with the male threads c, which fit the female threads d in the upper part of the ferrule e. h is a circular perforated disk placed in the ferrule'at a point just below the female threads d. f shows a movable plate having on its lower side a series of tapering pinsor pegs, g. These pass down through the perforations Zin the disk h, penetrate the bristles composing the brush, and expand the same within the ferrule. The lower end of the ferrule is first filled with the bristles necessary for the brush, the same passing up in said ferrule until they strike the l `disk h, which serves as a stop for their fartherl penetration. The movable plate f is then placed in the upper part of the ferrule and` its points g allowed to pass down through the perforations in the disk h and into the heads of the bristles forming the brush. The handle is then screwed into the ferrule until the-projecting part la of its base bears against the upper side of the plate f. The handle, continuing to be screwed down, forces with it the said plate and its points. This expands the bristles within the ferrule and holds the same securely therein. When they have become loosened by wear or otherwise the handle can be still farther The handle, with its base, neednot be made of solid material, but can be tubular, if desired. It may be made of metal, vulcanized rubber, or any suitable material.

It is evident from the foregoing that in al brush of this description, when the bristles have become so worn as to be unfit for further use, they can be removed from the ferrule and new ones inserted. It will, therefore, be seen thatmy improvement will last for a great length of time and for several sets of bristles.

While I have above described in detail a preferable method of constructing the brush, in order to carry out or embody my said invention, it is evident that the handle and ferrule may be made and adaptedl to each other in any ordinary and well-known way or method, and that in said case the operation and office of the said movable disk with projecting points would not be changed in any essential degree.

I do not claim a wedge placed in the center of the heads of the bristles, the said wedge being forced downward by screw-pressure, in order to expand and confine the bristles within the ferrule. having on its under surface a series of taper- I employ in lieu thereof a plate ing points which penetrate the heads of the bristles at regular distances apart, on their ends within the ferrule.

The advantage of this arrangement is very evident. Where a single wedge. is used, the pressure is unevenly distributed, the bristles in the center being more closely confined than those on the outer edge. By the use of my plate f the pressure is equally distributed among all the bristles. This, it will be seen, is quite an important feature.

I do not claim in a paint-brush a ferrule having a perforated diaphragm located in said ferrule to receive pegs driven through the same and into the butt of the bristles, for this, I am aware, is the invention of another.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. In a paint-brush, the movable and detachable plate f, having points on its lower surface, workin g within the ferrule e and held in place by the butt of the' brush-handle, substantially as described. l

2. In a paint-brush, the combination of a handle having a screw upon the butt, a ferrule with a female screw to match the screw upon the handle, a separate removable plate, f, having points g, the said plate f working within the ferrule and operated by the pressure of the handle, substantially as described.

3. The. combination of the screw-handle a, ferrule e fitted with a screw, the Aremovable platel f provided with points g, and a fixed perforated disk, h, the points of the plate f passing through the perforations of the disk h, and

kthe plate f being forced downward by theturning of the screw-handle, in order to force the points g into the heads of the bristles, as herein set forth. d

In testimony that I claim the foregoing as my own I afx my signature in presence of two witnesses.

Y FRANK H. JORDAN.
